The mechanical construction is very robust and neat.

The two MF 2 valves (tubes) in the LF stage are just on the right-hand side visible. For this occasion, these are mounted upside-down in their special sockets. The two RF stages are mounted in a kind of P-base-socket. The coil turret and its (side)contacts are visible in the centre upper part.
